With St. Patrick’s Day right around the corner, I’m seeing rainbows pop up all over the place. I’ve known that I wanted to try my hand at rainbow foods for a while now and knew this would be the perfect time for it and not just because I just threw a Rainbow Butterfly Unicorn Kitty party! Or because I’ve been dreaming about donut party ideas. While my son was hanging out with grandma all day, I decided to surprise him and make an entire rainbow full of his favorite food – colorful donuts with sprinkles on top. He’s such a picky eater and donuts are one of the few things he’ll actually eat. I’m planning to make these again on St. Patrick’s Day at the end of this leprechaun hunt scavenger hunt! Pretty sure I snuck an entire rainbow of donuts for myself while my son wasn’t watching. These were even better than the mini cheesecakes I made last year!

Ingredients
Ingredient Notes
Oil – you can use any unflavored oil such as vegetable oil, canola oil, or even avocado oil (although it’s a bit more expensive). Butter – you want to use unsalted butter that’s been melted and cooled. If you only have salted butter, omit the 1/4 tsp of added salt in the recipe. Food coloring – I recommend using gel in these so you don’t end up with added liquid from liquid food coloring. I used Chef Master Liqua Gel colors but any bright neon colors should work.
You’ll also need a donut pan for this recipe. I used a 3 inch donut pan like this one and that gave me about 14 donuts. You can also make bigger or smaller donuts but the number of donuts this recipe serves as well as the time they need to bake will need to be adjusted accordingly.
How to Make Rainbow Donuts
This donut recipe is easy to turn into rainbow donuts by simply adding a bit of food coloring into the batter and icing. I made six different colors – red, orange, yellow, blue, green, and purple – but you could use any color you want!
1 – make the rainbow donuts
Before you get started, preheat the oven to 350 degrees. If you’re using a metal donut pan, spray it with non-stick spray. If you’re using a silicone one, they should come out just fine without spraying. Start by mixing the melted butter, oil, and sugars together in a bowl just until mixed. Add eggs and vanilla into your butter mixture and whisk until fully mixed. Combine flour, baking powder, baking soda, salt, and nutmeg in a separate bowl and set it aside. Add half of the flour mixture into your butter mixture and stir just until you don’t see any dry flour – don’t over mix. Add in all of the buttermilk and stir. Then finish it off by adding the rest of the flour mixture – again don’t over mix. The batter will likely be a little lumpy and that’s okay! Split the batter into six bowls (for me it was about 127 grams per bowl if you want to be exact) and color one each of your rainbow colors using food coloring. Add one color batter to a piping bag. Repeat with the five other colors so you have six piping bags full of donut batter. You can also just spoon the batter into the donut pans, but the piping method gives you a lot more control. If you don’t have piping bags, you can also use zipper top bags with the corner cut off. Pipe the donut batter into the donut pan, filling about 3/4 of the way full with the batter. Don’t fill them completely or the batter will overflow and you’ll lose the hole in the donut. This recipe should give you enough to make two donuts per color with a few extra donuts to spare. Place the donut pan in the oven and bake for 10-12 minutes or until a toothpick inserted into the center comes out cleanly. Let the donuts cool in the pan for about five minutes then remove from the pan and allow to cool completely on a wire rack.
2 – make the icing
While the donuts are cooling, make a basic vanilla glaze by combining the powdered sugar and water until the mixture is smooth. If the mixture gets too runny, add another tablespoon of powdered sugar and stir again. If it gets too thick, add a teaspoon of water until you get your desired texture.
3 – decorate the donuts
Dip each cooled donut in the glaze then top with rainbow sprinkles or other ingredients as desired. Serve immediately and enjoy your rainbow treats! I mean how fun would these be with any other unicorn party decorations or boxed up as a prize for St. Patrick’s Day bingo!
Expert Tips
Try out different toppings! These would be delicious with Fruity Pebbles, drizzled with chocolate, or really topped with anything! Store any leftovers sealed in an airtight container for up to two days (but they are better fresh). Make your icing glaze thicker than you thick it needs to be so that it doesn’t just run right off the donuts. I always err on the side of thicker is better for these. Freeze the donuts before glazing them in a freezer safe airtight container. They can be frozen for up to three months and just brought to room temperature to enjoy when you’re ready.
